> (4/5) Deprecate i2c_client.id.

Now that i2c_client.id has no more users in the kernel (none that I
could find at least) we could remove that struct member. I however think
that it's better to only deprecate it at the moment, in case I missed
users or any of the other patches are delayed for some reason. We could
then delete the id member definitely in a month or so.

(3/5) Stop using i2c_client.id in misc drivers.

Affected drivers:
* acorn/char/pcf8583
* acorn/char/i2c
* i2c/i2c-dev
* macintosh/therm_windtunnel
* sound/oss/dmasound/dac3550a
* sound/ppc/keywest

The Acorn pcf8583 driver would give the i2c_client id the same value as
the i2c_driver id, and later test that client id (in i2c). I changed it
to test the client's driver id instead. The result is the same and the
client id is then useless and can be removed.

All other drivers here would allocate the client id to some value and
then never use it. They are unaffected by the change.

(2/5) Stop using i2c_client.id in media/video drivers.

Affected drivers:
* adv7170
* adv7175
* bt819
* bt856
* bttv
* cx88
* ovcamchip
* saa5246a
* saa5249

* tda7432
* tda9840
* tda9875
* tea6415c
* tea6420
* tuner-3036
* vpx3220

Most drivers here would include the id as part of their i2c client name
(e.g. adv7170[0]). This looks more like an habit than something really
needed, so I replaced the various printf by strlcpy, which should be
slightly faster. As said earlier, clients can be differenciated thanks
to their bus id and address if needed, so I don't think that including
this information in the client name is wise anyway.

Other drivers would either set the id to -1 or to a unique value but
then never use it. These drivers are unaffected by the changes.

(1/5) Stop using i2c_client.id in i2c/chips drivers (mostly hardware
      monitoring drivers).

Drivers affected:
* adm1021
* adm1025
* adm1026
* adm1031
* ds1621
* fscher
* gl518sm
* isp1301_omap
* lm75
* lm77
* lm80
* lm83
* lm85
* lm87
* lm90
* max1619
* pcf8574
* pcf8591
* rtc8564
* smsc47m1
* w83l785ts

The vast majority of these drivers simply defined the i2c_client id
struct member but never used it, so they are not affected at all by the
change. Exceptions are:

* lm85 and rtc8564, which would at least display the id in a debug
message when assigning it. Not really useful though, as the id was then
never used.

* adm1026, which used the assigned id in all driver messages. However,
since dev_* calls will append the bus number and client address to these
messages, the id information is redundant and can go away. Also, the
driver would allow some GPIO reprogramming on the first client only
(id=0) and removing the id doesn't allow that anymore. I would restore a
similar functionality if needed, but the ADM1026 chip is found on very
few motherboards and none of these has more than one ADM1026 chip AFAIK,
so it doesn't seem to be worth the effort.

Here comes this patch. The new "fix_pwm_polarity" module parameter

supported in the case the original PWM configuration is suspected to be
bogus, and only if we think that reconfiguring the chip is safe.

This patch adds support for detecting and working around a bug in
the A2 rev of the Exar ST16C2550 UART.  The chip incorrectly
advertises an EFR and mis-detects as having the wrong size FIFO.
Much of the patch below is Russell's proposed solution to the
problem.  The only changes I've made are to check the FIFO size
on the part (because there is a real part with the same divisor
ID and larger FIFO) and save and restore the LCR register around
the size_fifo() routine (it doesn't work correctly with a LCR
value of 0xBF).

The pipe code has traditionally not cared about which end-point of the
pipe you are polling, meaning that if you poll the write-only end of a
pipe, it will still set the "this pipe is readable" bits if there is
data to be read on the read side.

That makes no sense, and together with the new bigger buffers breaks
python-twisted.
